Reheating Furnace Thermal Stress Analysis Presented at ASME Summer Heat Transfer Virtual Conference 2020
September 2, 2020
CIVS Graduate Research Assistant Francisco J. Martinez represented CIVS to present the research paper titled “Numerical Analysis of Thermal Stress Development of Steel Slabs in a Pusher-Type Reheat Furnace” at the ASME (American Society of Mechanical Engineers) Summer Heat Transfer Virtual Conference on July 15th, 2020.
Crack formation and propagation constitute a real issue for the hot rolling process which can produce economic hardships as well as operational delay. This research study was focused on modeling the stress caused during the heating process of steel slabs. The highest levels of stress were located at the preliminary stage of the preheating heating zone. The main influence on mechanical stress generation in the slabs was found to consistently relate to the temperature gradients in said slabs. Temperature and stress distributions from the simulation were found to have a good agreement with industry-provided data. Higher charge temperature improved the overall reheating process efficiency by reducing the magnitude of tensile and compressive stresses.
The ASME Summer Heat Transfer Conference is designated to provide a forum for presentation of state-of-the-art research and opportunities for technical interactions among participants. The conference will bring together international researchers and engineers focusing on heat and mass transfer in a variety of applications.
